AbstractIn this research, we examined effects of higher versus lower threat contexts on attention biases in more and less pain-fearful chronic pain subgroups via eye-tracking methodology. Within a mixed chronic pain sample (69 women, 29 men), biases in orienting and maintenance of visual attention were assessed during the standardized image pair presentation phase (2,000 ms) of a modified visual dot probe task featuring painful-neutral (P-N) image pairs (lower threat context) and a parallel task in which these P-N pairs cued potential pain (higher threat context). Across both tasks, participants more often oriented toward, gazed longer at, and made more unique fixations upon pain images during P-N pair presentations. Although trait-based fear of pain was not related to any gaze bias index in either task, between task analyses indicated the sample reported more state fear, directed their initial gaze less often, and displayed longer overall gaze durations toward pain images in the higher threat context in which P-N trials signaled potential pain. Results supported the threat interpretation model premise that persons with chronic pain have difficulty disengaging from moderately threatening visual painful cues.Copyright © 2018 The American Pain Society.
